If that is the correct game score, then Adams resigned in a possibly winning
(and certainly better) position:

38.Rg1 Nb5?

   [38...Bf8! 39.Nf5 Ne6 40.Bxe6 fxe6 41.Nd4 Bxb4 +=]

   [38...Bxb4 39.Qf4 Rg7
       (39...Qa7 40.Rg5 (40.Nf5 Bf8 =) 40...Qc5 41.Bf5 Rg7 42.e6 +-)
       (39...Qa5 40.Rg5 Rg7 (40...Rbd8 41.Rbg1 and White mates) 41.Nc2 +-)
    40.Nf5! gxf5 41.Bxf5+ Kg8 42.Qh6 Ne6 43.Rxb4 Qxb4 44.c7 Re8 45.Qh7+ Kf8
    46.Qh8+ Ke7 47.Qxe8+ Kxe8 48.c8Q+ +-]

39.Nf5 gxf5 40.Bxf5+ Rg6 41.Qxd5 Rf8 42.e6? {Did Ivanchuk really play this??}

   [42.Qe4 Rfg8 43.e6 Nd6 44.exf7 Nxe4 45.fxg8Q+ Kxg8 46.Rxg6+ Kf7 47.Bxe4 +-]

42...Nd6

   [or 42...Kh6 =]

43.exf7? {Black resigned here??} Nxf5 44.Qxf5 Qxc6 45.b5 Qe6 -/+
